[0023] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0024] See also Figures 1 to 6 A miniature toggle switch includes a switch body 1, wherein the switch body 1 includes a toggle assembly 11, a contact assembly 12 connected to the toggle assembly 11, and a shell 13 for fixing the toggle assembly 11 and the contact assembly 12. The length of the switch body 1 is between 15mm and 30mm, the width is between 5mm and 10mm, and the height is between 5mm and 10mm. With such a design, the toggle switch is smaller in size and can be used in some smaller electronic devices. The miniature toggle switch adopts advanced manufacturing technology and materials, such as micro stamping, precision injection molding and high-performance alloys, to ensure that the toggle switch has good electrical performance, mechanical stability and a long service life while being miniaturized, effectively improving the practicality of the toggle switch. Furthermore, the toggle switch within this specification range can be used in a 3A125VAC circuit environment.

[0025] Further, see Figures 1 to 6, a miniature toggle switch, the contact assembly 12 includes a terminal board 121 connected to the housing 13, and a plurality of contact strips 122 provided on the terminal board 121, the terminal board 121 is provided with a plurality of sockets 1211 for the contact strips 122 to pass through, the contact strips 122 include contact terminals 1221 abutting against the sliding contact clamp 112, and conductive terminals 1222 electrically connected to the outside, the cross-sectional length of the contact terminal 1221 in the horizontal direction is greater than the length of the socket 1211 in the horizontal direction, and the cross-sectional length of the conductive terminal 1222 in the horizontal direction is less than or equal to the cross-sectional length of the socket 1211 in the horizontal direction. The socket 1211 on the terminal board 121 is used to accommodate the contact strip 122, and the contact strip 122 includes the contact terminal 1221 and the conducting terminal 1222. The conducting terminal 1222 is used to connect to the external circuit, and its horizontal cross-sectional length is less than or equal to the horizontal cross-sectional length of the socket, which means that it can smoothly pass through the socket 1211 and extend to the other side of the terminal board 121 to be welded or crimped with other electronic components. The contact terminal 1221 is used to contact the sliding contact clip 112, and its horizontal cross-sectional length is greater than the horizontal cross-sectional length of the socket 1211, which means that the contact terminal 1221 cannot pass through the socket 1211, so that the contact terminal 1221 is fixed on the upper side of the terminal board 121 and the conducting terminal 1222 is exposed on the outside of the toggle switch.

[0026] Further, see Figures 1 to 6A miniature toggle switch, the toggle assembly 11 includes a toggle block 111, a plurality of sliding contact clips 112 connected to the toggle block 111, a first elastic body 113, and a ball 114. A toggle rod 1111 is provided on one side of the toggle block 111, a positioning hole 1112 is provided on one side of the toggle block 111, the first elastic body 113 and the ball 114 are arranged in the positioning hole 1112, the toggle block 111 is provided with the same number of accommodating cavities 1113 as the sliding contact clips 112, the sliding contact clips 112 are installed in the accommodating cavities 1113, and the sliding contact clips 112 are connected to the contact terminals 1221. The user uses the toggle rod 1111 to toggle the toggle block 111 to switch the state of the switch, and the sliding contact clip 112 establishes or breaks contact with the contact terminal 1221 when the toggle block 111 moves, thereby changing the state of the circuit. Furthermore, the positioning hole 1112 provides an installation position for the first elastic body 1123 and the ball 114. The first elastic body 113 and the ball 114 provide a self-resetting mechanism, which can ensure that the ball 114 always remains in contact with the housing 13, while enhancing the operational feel and reliability of the toggle switch. Through the coordinated work of the above components, the toggle assembly 11 can effectively interact with the contact assembly 12 to achieve circuit switching, effectively improving the reliability and practicality of the toggle switch.

[0027] Further, see Figures 1 to 6, a miniature toggle switch, a circular hole 11131 is provided in the accommodating cavity 1113, the toggle assembly 11 also includes a plurality of second elastic members 115 provided in the circular hole 11131, one side of the second elastic member 115 abuts against the sliding contact clip 112 and the other side abuts against the bottom surface of the circular hole 11131, a first protrusion 1121 and a second protrusion 1122 are provided on the lower side of the sliding contact clip 112, the first protrusion 1121 and the second protrusion 1122 abut against the contact strip 122, the length and width of the accommodating cavity 1113 are respectively greater than or equal to the length and width of the sliding contact clip 112, and the diameter of the circular hole 11131 is greater than or equal to the diameter of the second elastic member 115. The circular hole 11131 is located in the accommodating cavity 1113, and is used to accommodate the second elastic member 115. The second elastic member 115 abuts against the sliding contact clip 112, and the other side abuts against the bottom surface of the circular hole 11131. The second elastic member 115 provides a pre-tightening force for the sliding contact clip 112 to ensure that there is sufficient pressure when the sliding contact clip contacts the contact terminal 1221, thereby ensuring a good electrical connection. Secondly, the design of the first protrusion 1121 and the second protrusion 1122 can ensure that the sliding contact clip 112 can accurately contact different contact terminals 1221 during movement, thereby realizing circuit switching and effectively improving the reliability of the toggle switch.

[0028] Further, see Figures 1 to 6 A miniature toggle switch comprises at least two groups of contact bars 122, each group comprising at least four contact bars 122. The contact bars 122 within each group are spaced uniformly apart. The design of at least two groups of contact bars 122 means that the toggle switch can simultaneously control two or more independent circuits, meeting the need to integrate multiple control functions into a single device, such as complex electronic equipment and industrial control systems. The design of at least four contact bars 122 per group allows the toggle switch to achieve more complex functions, not only simply opening or closing a circuit but also selecting different circuit paths and combinations as needed, effectively improving the practicality and functionality of the toggle switch.

[0029] Further, see Figures 1 to 6 A miniature toggle switch is provided, wherein a guide bar 1114 is provided on one side of the toggle block 111 provided with the toggle rod 1111, and the guide bar 1114 abuts against the housing 13. The guide bar 1114 reduces the contact area between the toggle block 111 and the housing 13, thereby reducing the lateral friction of the toggle block 111 during movement, thereby reducing the resistance encountered when the toggle block 111 is toggled, and reducing the wear between the toggle block 111 and the housing 13, thereby extending the service life of the toggle switch.

[0030] Further, see Figures 1 to 6 A miniature toggle switch is provided, wherein a first slot 1213 is provided on the side of the terminal board 121 and a second slot 1212 is provided on the lower side. A mating portion 131 is provided on the lower side of the housing 13. The mating portion 131 includes a snap-fitting portion 1311 that matches the first slot 1213 and a buckle 1312 that is connected to the snap-fitting portion 1311 and abuts against the bottom surface of the second slot 1212. With such a design, the mating of the first slot 1213 and the snap-fitting portion 1311 provides horizontal positioning and constraint, fixing the horizontal positional relationship between the housing 13 and the terminal board 121, while the mating of the second slot 1212 and the buckle 1312 provides vertical positioning and constraint, fixing the vertical positional relationship between the housing 13 and the terminal board 121, so that the housing 13 and the terminal board 121 form a whole, effectively improving the integrity and stability of the toggle switch.

[0031] Further, see Figures 1 to 6 A miniature toggle switch is provided. The housing 13 has a lever hole 132 on one side and a plurality of limiting holes 133 on the other side. The limiting holes 133 abut against the ball bearings 114. The lever hole 132 allows the lever 1111 to be exposed and controls the range of motion of the lever 1111. The position of each limiting hole 133 corresponds to each gear position of the toggle switch. The limiting holes 133 are used to define the position of the ball bearings 114, providing a stable positioning point for the toggle block 111, preventing vibration of the toggle switch from causing poor contact between the sliding contact clip 112 and the contact terminal 1221, and effectively improving the stability and reliability of the toggle switch.

[0032] Further, see Figures 1 to 6 A miniature toggle switch, wherein the number of the limiting holes 133 is at least three, and the center distance between the two limiting holes 133 located at the two ends is the maximum movable distance of the toggle assembly 11. With this design, the number of the limiting holes 133 is at least three, which means that the toggle switch has at least three gears. Furthermore, the design of the center distance between the limiting holes 133 located at the two ends being the maximum movable distance of the toggle assembly 11 makes the two outer limiting holes 133 the boundaries of the toggle switch travel, ensuring that the toggle assembly 11 can only move within a preset range, effectively preventing damage to the toggle switch or electrical connection abnormalities caused by excessive toggle, and effectively improving the safety and reliability of the toggle switch.

[0033] Further, see Figures 1 to 6In a miniature toggle switch, the upper surface of the contact terminal 1221, the first protrusion 1121, and the second protrusion 1122 are arcuate. Designing the first protrusion 1121 and the second protrusion 1122 as arcuate surfaces reduces friction between the sliding contact clip 112 and the contact terminal 1221, making the switch action smoother and reducing wear, effectively extending the service life of the switch.

[0034] Working principle: The sliding contact clip 112 is installed in the accommodating cavity 1113, and the sliding contact clip 112 is connected to the contact terminal 1221. When the toggle block 111 is moved until the ball 114 falls into the limiting hole 133, the sliding contact clip 112 is connected to the two contact terminals 1221 at the corresponding positions. At this time, the circuit connected to the corresponding two conductive terminals 1222 is connected.
